Live Stage: Practical Sound Analysis [es Barcelona]

olaf.jpgPractical Sound Analysis :: with Fredrik Olofsson :: October 28-30, 2011, 18:00-22.00h :: Hangar. Passatge del Marquès de Santa Isabel, 40. Barcelona. Metro Poble Nou. :: Price: 90€ (or cheaper as part of the whole course) :: prior knowledge of basic sound synthesis is assumed ::

This seminar will give an overview of several sound analysis techniques and guide participants on how to apply them to control sound or music processes. We will experiment with techniques for pitch detection and envelope tracking and will also cover more advanced algorithms, such as event and chord identification. We will also look at the importance of filtering and mapping the resulting data prior to using it to drive various synthesis parameters in realtime.

Session #01: Friday 28.10.2011, 18:00-22.00h. Introduction to sound analysis, with applications and examples. Overview of common techniques: envelope, pitch and timbre tracking beat; tempo and event detection; feature extraction and sound recognition. Practical exercise

Session #02: Saturday 29.10.2011, 11:00–14:00h, 16:00-19:00h :: Time-domain approaches, with focus on amplitude and pitch tracking. Scaling, filtering and mapping sound analysis data. Frequency-domain approaches, with focus on onset detection and timbre analysis. Driving synthesis processes with data obtained from sound analysis. Practical exercise

Session #03: Sunday 30.10.2011, 11:00–14:00h, 16:00-19:00h :: Introduction to the Fast Fourier Transform. The Phase Vocoder. Tracking harmonic partials. Low-level feature extraction vs high-level descriptors. Chord tracking and other advanced topics. Practical exercise

Fredrik Olofsson was trained as a composer at the Royal University College of Music in Stockholm. As part of MusicalFieldsForever he has exhibited interactive art at museums and galleries. He currently teaches at the University of Arts of Berlin and is a frequent contributor within the SuperCollider open source community. He is also one of the founding members of TOPLAP, a collective that popularized the use of live coding.

Level: intermediate (prior knowledge of basic sound synthesis is assumed: envelopes, oscillators, filters)
